HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 339,187, dated April 6. 1886.

Serial No. 187,716. (No model.)

To all whom it may concern:

Be it known that we, CHARLES E. HUNT, NATHAN B. HELM, and HENRY L. Framers, each a resident of Harvard, in the county of McHenry and State of Illinois, haveinvented certain new and useful Improvements in Hay Elevators and Carriers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to hay elevators and carriers, and especially to devices for transferring a hay-carrier pulley from one end to the other of the track on which the carrier is operated.

This invention is an improvement upon a similar device which is shown, described, and claimed in our Letters Patent No. 316,462,

dated April 28, 1885.

The present invention is fully described and explained in the following specification, and shown in the accompanying drawings, in which Figure 1 is a side elevation of the frame of a barn or otherbuilding, a carrier and carriertrack in place within the building, and our improved pulley-transferring device in operative position with reference to the carrier and 0 track; Fig. 2, a plan of the carrier-track and carrier, with the pulley-transferring device, and the rafter to which is attached the eyeplate H H; Fig. 3, an elevation of the pulleyring G, by means of which the pulley may be 3 5 attached to the hook at either end of the track.

In these views, M is the ridge-pole; M is the side plate; N N are the end-rafters, and B is one of the central rafters of an ordinary barn-frame, and A is a carrier track of any desired cross-section suspended in the barn below the ridge-pole and held in place by any well-known means.

K is a hay elevator and carrier, provided with wheels or rollers, which rest on the track 4 5 and support the carrier. V is a rope for operating the elevator. L is a pulley attached to a fork of suitable construction, and supported by the rope V, and I is a pulley adapted to be flattened in place at or near either end of the carrier-track, and to receive the rope V for the purpose of moving the carrier from the center of the track toward either end thereof.

On the side of the track A, and near the opposite ends thereof, are securely fastened 5 two castings, G 0, provided at their lower edges with books F F, which extend toward the center of the track. The points of the hooks arejoined by a pulley-track, T, of wire or other suitable material, and the hooks set oif sufficiently from the carriertrack A that neither the pulley-track nor the pulley passing along it can interfere with the carrier. On each of the castings O O is a loop or ear,

D D, and in these loops are mounted grooved pulleys, E E, whose use will be explained hereinafter. The pulley I is provided with a ring, G, having at its upper margin an ear or enlargement, G, which is formed with two openings, G, for the insertion of the ends of 0 acord,U U U U U. The central portion of this cord forms a loop, U",which hangs within convenient reach of the floor of the barn, and

its ends are carried first through two integrally-formed eyes, H H, fastened to the lower 7 face of a rafter B, and thence over the grooved pulleys E E and through the openings G, when they are fastened by knotting the ends or otherwise. When the carrier is in operation, the ring G lies in one of the hooksF F. 8c As shown in the drawings, it is in the hook F; but it may be transferred to the opposite hook,

F, by first tightening the part U of the cord until the ring is lifted from the hook, and then drawing the part U of the cord and moving the ring along the pulley -track T until it reaches and enters the hook F. The reversal of this operation transfers the ring from the hook F to the hook F.

\Ve have found in practice that the pulley- 0 track T may be dispensed with and the pulley moved from one supporting-hook to the other by holding the ,cord U U U U U taut. \Ve do not intend, therefore, to limit our invention by making the pulley-track an indis- 5 pensable element thereof.

The device shown and described herein differs from that shown in our patent above referred to in the following particulars: In the present device we have united in a single struc roo avoiding liability to mistake.

our former patent.

"single eye or staple shown in our former patture the hook 'F and the pulley D, and its housing, whereas in our former construction we used'a hook and a separate eye or staple for the cord to pass through. The operation of the two devices is the same; but we have found that where the device is-to be put in place by inexperienced persons, it is an advantage to have the parts put together at the factory in fixed relative positions, thereby For the same reason we have found it advisable to fasten the parts to the carrier-track as shown'herein, instead of to the end of the barn, as shown in The double eye H H, fastened to the rafter, is an improvement on the cut, in that it prevents the twisting of the cord, and thus prevents mistakes in drawing the wrong fold of the cord in operating the transferring device. 7

It will be seen that these improvements constitute no change in the principle of the device shown in and covered by our former patent, but that they all tend in the direction of definiteness in its application and operation, and thus obviate the possibility of mistake when the device is placed in wholly unskilled hands, as it often must be.

Having now described and explained our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with a track forhay carriers, of two pulley-supports attached to the track near the opposite ends thereof, and means, substantially as shown and described, for detaching a pulley from one of said supports and transferring it to the other.

2. The combination, with a carrier-track,

of two pulley-supporting hooks fastened to the track near its opposite ends, and means, substantially as shown and described, for lifting a pulley from one of said hooks and transferring it to the other.

3. The combination, with a carriertrack, of two castings fastened to the track near its opposite ends, and each provided with a pulley-supporting hook, two pulleys mounted on said castings, respectively, above said hooks, a pulley-ring adapted to engage either of said hooks, and a cord having its ends fastened to said ring and passing over said pulleys and through a suitable stationary eye or eyes, substantially as and for the purpose set forth.

4.. The combination of the track A, the castings O 0, provided with hooks F F, the pulleys E E, mounted on said castings, the pulley-ring G, and stationary eyes H H, and the cord passing through the eyes H H, over the pulleys E E and having its ends fastened to the ring G.

5. The combination of the track A, the castings O G, fastened thereto and having hooks F F, the pulleytrack T, joining said books, the pulleys E E, mounted on the cast ings O G, and the cord passing through stationary eyes and over the pulleys E E and having its ends fastened to a pulley or pulleyring, substantially as shown and described, and for the purpose set forth.

In testimony whereof we have signed this specification in the presence of, two subscribing witnesses.
